Recent update: I have been getting this error and none of the solutions listed at the link you provided work (the linked webpage was last updated in 2011). Maybe there is a more current issues with new versions of the software not addressed in that article. When I deleted the contacts from my Outlook program, they promptly disappeared from all of my devices and iCloud account. Glad I could restore. I have also un-installed my install of iTunes and restored both of my iOS devices and rebuilt them as new devices - none of those steps seem to make any difference. I suspect that there must be corrupted files on my machine that never get fully removed, recreating my iTunes library is a royal pain. Any updated solutions that involve the iCloud?
I'm having similar problems as CRM813, with none of the online solutions proving successful. Any help or new tips would be appreciated!
I too have got the same problem and it only arose this afternoon/evening (GMT).
All online solutions prove unsuccessful, have removed all Apple software (except safari) from Windows host and re-installed, same problem exists... no synch working with any device.
I Am also having this issue from today, never had it before. Read alot about Xcode and i dont even know what that was. First it synced my wifes ipad then this error and now nothing. If i see the same link for fix again im gonna go nuts, none of it works. im about to do a total restore of my laptop, can anyone else recommended something new before i do. Please dont paste the same link about uninstall in this way and clear out you folders that way.
I have the same issue - started yesterday afternoon and now cannot resolve. Something must have changed yesterday (overnight USA) with Apple's servers.
Same problem, and the solution offered (above) doesn't work
I'm having the same problem too, have tried solutions on the link and none of them work. Must be since the last itunes update as it's the first time I've plugged my iphone in since then!
So, after following the suggestions in this posting, https://discussions.apple.com/thread/3947215?answerId=18373231022#18373231022, I can safely say that that's had absolutely no effect whatsoever other than waste nearly an hour of my time in the uninstallation and re-installation processes.....
Something has to have changed either on the Apple side, or the Microsoft side, to have had this wonderful effect of not being able to sync/backup my iDevices!!!!!
Is there any way to bring this thread to the attention of someone that can help us? Other than just posting? Mine had stopped working before the most recent itunes update but again only started yesterday :S no idea what's going on!
I have just started to get the same message also - O.K. yesterday - today has been a complete waste of my time trying to get both my i-pad and i-phone to sync
I agree with TreenyLeonard - how do we escalate this to someone in Apple who can provide a definitive solution quickly?
For what it's worth, I've just provided feedback through iTunes... don't know where that feedback will go, but clearly some sort of update has been pushed out by either Apple or Microsoft to cause this.
Since installing the upgrade this morning, I have had this problem too. Nothing suggested is making it better, have even tried reinstalling. Hope a further update is released really soon to make this workable again?
Nice One StuRob - I've just finished my feedback through i-Tunes also. I agree with you - some update has caused this.
